Protein characterization

Do you need customized protein characterization services? For instance, for identification, quantification, and sequencing of your biopharmaceutical protein and its product-related impurities?

Or are you looking to analyze process-related impurities, e.g., Host Cell Proteins (HCPs), throughout your purification steps and clinical GMP batches?

What can you achieve with mass spectrometry-based characterization?

• Confirm your protein sequence and find sequence variants and degradation products. Analyze protein stability and quantify modifications.
• Or find the HCP ELISA with the highest coverage for your drug and process HCPs.
• Also, you can get the identity and quantity of all individual proteins in your samples, including residual HCPs.

We have optimized our protein analysis services for a wide range of protein-based biologics. With experience from thousands of analytical runs and 350+ HCP analysis projects, we are an experienced protein characterization CRO. And we offer established and validated workflow for most expression systems and sample types.

Standard or customized protein characterization

You can customize the analyses to fit your specific protein product to strengthen your process development and production throughout the project. You can choose and combine your preferred analysis package from the services below. Or, you can send us your project description to design the analysis package that meets your needs.

We conduct all protein analyses according to the ICH Q6B guidelines – Test Procedures and Acceptance Criteria for Biotechnological/Biological Products. All repetitive tasks are automated. This way, you have ensured high reproducibility and fast reporting time.

Depending on your project needs, you can select one or combine several protein characterization analyses from the list below.
